Role of formative assessment in predicting academic success among GP registrars: a retrospective longitudinal study

Objectives The James Cook University General Practice Training (JCU GPT) programme’s internal formative exams were compared with the Royal Australian College of General Practitioners (RACGP) pre-entry exams to determine ability to predict final performance in the RACGP fellowship exams. Design A retrospective longitudinal study. Setting General Practice (GP) trainees enrolled between 2016 and 2019 at a Registered Training Organisation in regional Queensland, Australia. Participants 376 GP trainees enrolled in the training programme. Exposure measures The pre-entry exams were Multiple-Mini Interviews (MMI), Situational Judgement Test (SJT) and Candidate Assessment and Applied Knowledge Test. The internal formative exams comprised multiple choice questions (MCQ1 and MCQ2), short answer questions, clinical skills and clinical reasoning. Primary outcome measure The college exams were Applied Knowledge Test (AKT), Key Feature Problems (KFP) and Objective Structured Clinical Examination (OSCE). Results Correlations (r), coefficients of determination (R2) and OR were used as parameters for estimating strength of relationship and precision of predictive accuracy. SJT and MMI were moderately (r=0.13 to 0.31) and MCQ1 and MCQ2 highly (r=0.37 to 0.53) correlated with all college exams (p<0.05 to p<0.01), with R2 ranging from 0.070 to 0.376. MCQ1 was predictive of failure in all college exams (AKT: OR=2.32, KFP: OR=3.99; OSCE: OR=3.46); while MCQ2 predicted failure in AKT (OR=2.83) and KFP (OR=3.15). Conclusion We conclude that the internal MCQ formative exams predict performance in the RACGP fellowship exams. We propose that our formative assessment tools could be used as academic markers for early identification of potentially struggling trainees

Key elements of effective postgraduate GP educational environments: a mixed methods study

Objectives Evidence in the literature suggests that satisfaction with postgraduate general practice (GP) training is associated with the quality of the educational environment. This study aimed to examine GP registrars’ level of satisfaction with a distributed model of training in a regional educational environment and investigate the relationship between satisfaction and academic performance. Study design A longitudinal 3-year study was conducted among GP registrars at James Cook University using a sequential explanatory mixed methods research design. GP registrars’ satisfaction was obtained using the scan of postgraduate educational environment domains tool. A focus group discussion was conducted to explore GP registrars’ perceptions of satisfaction with the educational environment. Setting James Cook University General Practice Training (JCU GPT) programme. Participants Six hundred and fifty one (651) GP registrars enrolled between 2016 and 2018 at JCU GPT programme. Results 651 registrars completed the satisfaction survey between 2016 and 2018. Overall, 92% of the registrars were satisfied with the educational training environment. Registrars who had become fellows reported higher satisfaction levels compared with those who were still in training (mean=4.39 vs 4.20, p=0.001). However, academic performance had no impact on level of satisfaction with the educational environment. Similarly, practice location did not influence registrars’ satisfaction rates. Four themes (rich rural/remote educational environment, supportive learning environment, readiness to continue with rural practice and practice culture) emerged from the thematic data analysis. Conclusion A clinical learning environment that focuses on and supports individual learning needs is vital for effective postgraduate medical training. This study suggests that JCU GPT programme’s distributed model fostered a satisfying and supportive training environment with rich educational experiences that enhance retention of GP registrars in rural/remote North Queensland, Australia. The findings of this study may be applicable to other settings with similar training models

Between Andes and Amazon: The genetic profile of the Arawak-speaking Yanesha

The Yanesha are a Peruvian population who inhabit an environment transitional between the Andes and Amazonia. They present cultural traits characteristic of both regions, including in the language they speak: Yanesha belongs to the Arawak language family (which very likely originated in the Amazon/Orinoco lowlands), but has been strongly influenced by Quechua, the most widespread language family of the Andes. Given their location and cultural make-up, the Yanesha make for an ideal case study for investigating language and population dynamics across the Andes-Amazonia divide. In this study, we analyze data from high and mid-altitude Yanesha villages, both Y chromosome (17 STRs and 16 SNPs diagnostic for assigning haplogroups) and mtDNA data (control region sequences and 3 SNPs and one INDEL diagnostic for assigning haplogroups). We uncover sex-biased genetic trends that probably arose in different stages: first, a male-biased gene flow from Andean regions, genetically consistent with highland Quechua-speakers and probably dating back to Inca expansion; and second, traces of European contact consistent with Y chromosome lineages from Italy and Tyrol, in line with historically documented migrations. Most research in the history, archaeology and linguistics of South America has long been characterized by perceptions of a sharp divide between the Andes and Amazonia; our results serve as a clear case-study confirming demographic flows across that \u2018divide\u2019

T Regulatory Cells Are Markers of Disease Activity in Multiple Sclerosis Patients

FoxP3+ Treg cells are believed to play a role in the occurrence of autoimmunity and in the determination of clinical recurrences. Contradictory reports are, however, available describing frequency and function of Treg cells during autoimmune diseases. We examined, by both polychromatic flow cytometry, and real-time RT-PCR, several Treg markers in peripheral blood mononuclear cells from patients with multiple sclerosis (MS), an autoimmune disease affecting the central nervous system. We found that Tregs, as defined by CD25, CD39, FoxP3, CTLA4, and GITR expression, were significantly decreased in stable MS patients as compared to healthy donors, but, surprisingly, restored to normal levels during an acute clinical attack. We conclude that Treg cells are not involved in causing clinical relapses, but rather react to inflammation in the attempt to restore homeostasis

An African Ancestry-Specific Allele of CTLA4 Confers Protection against Rheumatoid Arthritis in African Americans

Cytotoxic T-lymphocyte associated protein 4 (CTLA4) is a negative regulator of T-cell proliferation. Polymorphisms in CTLA4 have been inconsistently associated with susceptibility to rheumatoid arthritis (RA) in populations of European ancestry but have not been examined in African Americans. The prevalence of RA in most populations of European and Asian ancestry is ∼1.0%; RA is purportedly less common in black Africans, with little known about its prevalence in African Americans. We sought to determine if CTLA4 polymorphisms are associated with RA in African Americans. We performed a 2-stage analysis of 12 haplotype tagging single nucleotide polymorphisms (SNPs) across CTLA4 in a total of 505 African American RA patients and 712 African American controls using Illumina and TaqMan platforms. The minor allele (G) of the rs231778 SNP was 0.054 in RA patients, compared to 0.209 in controls (4.462×10−26, Fisher's exact). The presence of the G allele was associated with a substantially reduced odds ratio (OR) of having RA (AG+GG genotypes vs. AA genotype, OR 0.19, 95% CI: 0.13–0.26, p = 2.4×10−28, Fisher's exact), suggesting a protective effect. This SNP is polymorphic in the African population (minor allele frequency [MAF] 0.09 in the Yoruba population), but is very rare in other groups (MAF = 0.002 in 530 Caucasians genotyped for this study). Markers associated with RA in populations of European ancestry (rs3087243 [+60C/T] and rs231775 [+49A/G]) were not replicated in African Americans. We found no confounding of association for rs231778 after stratifying for the HLA-DRB1 shared epitope, presence of anti-cyclic citrullinated peptide antibody, or degree of admixture from the European population. An African ancestry-specific genetic variant of CTLA4 appears to be associated with protection from RA in African Americans. This finding may explain, in part, the relatively low prevalence of RA in black African populations
